Bait-known that I, AM'os H. SMrrH, a citizen""of the United States, residing at the boroughofBronx, in the city of New York, county of Bronx, and State of New York, have invented certain new and useful Im- "ifirovements in Dcmountable Rims for Yeicle-Wheels, of which the followipgis a sgecificatiom'reference being had therein to accompanying drawings, which form a part thereof.

My invention relates to demountable rims for. vehicle wheels and more particularly to a type thereof adapted tobe removed from the wheel in its entirety to facilitateitlie removal of the tire from a wheel or the mounting of the tire thereupona Rims of this character are so designed as to be mounted upon or removed from the vehicle-wheel with the shoe in position thereon, and are frequently composed ofindependent separable sections so assembled as to a permit the removal hone of these sections laterally as to the other to afford that clearance necessary to ermit the mounting of the shoe' and the con ained inner tube, upon .or

tl'ieir-r'emoval from, the'said rim. Heretofore the'construction of rims of this character has been such as to require considerable time, and l'abor, to efltectthe removal of the rim from the wheel and the removal of the tire from the rim; Bymy invention Iprovide 'arim so constructed to sccurea permanent fshort circumferential movement of ohe of" the section's relative. to the other to permit relation of' the sections thereot'with relation to each other, and to the telly of the wheel, while in use, and yet permit these ctions tobe' rea'dilyjemo'ved from the feliygan'd quickly separated, to facilitate the mounting V of the tire therein, or its removal'therefi'om. i The rim is soiconstructed; as to require a 5 the uniting'or separating of these parts, each section being provided 7 with independent 'Iwh ereby movement ofeitherorbothfsections'circumferentially of the wheel is'premeans coiiperating with the wheel felly vented when rim is in place thereon. The rim'is also so constructed as to be supported ulong'both edges thereof. The two sections of said demountable' rim are so constructedandarranged as to permit the necesairy relative circumferential and lateral movement thereof, to effect the disconnectioii and separation of the sections without s ecimen orgtemn Patent. amas-111.4 June 16, 1915.

likelihood of injlirytq the, valve stem. The

two sectio'us'of the rim are so constructed as to permit the application thereto of sufficient power to impart that circumferential movement ofi thesections relatiy'ely to each other,

parts as to permit the separation thereof. This circumferential movement is secured by means oil sand levers adapted to act upon projections or studs carried respectively tions of the rim, tion of power for by the two sec-- thus limiting the applicasecuring the relative movesingle point. Incidentally, the circumferential movement of the two sections relatively to each other, will have the efi'ect of preventing the formationof a bond between these sectionsaft'er prolonged use. To minimize the binding of the two sections, I preferably so construct these sections as to restrict the contact area of one with the other to as small 'conlinuo-ussurface closing the space between a the beads of the "tire shoe, thus avoiding all possibility of the pinching,

and resultant puncture, of the inner tube when mounting rim. The outer face of the base'fla'ngc of thatsection forming the bot tom of the rim channel,- has no openings ther'einexcepting that necessary for the insertion of the valve stem, and the various studs carried by this sectiolrdo not extend beyond said surface in a degree toPreser'it any projectio'ns which would have a tendency to liljlll'? the inner tube in any way.

The invention consists primarily in a demountable rim for vehicle wheels embodying therein two separable, circular sections each having, a side flange and a base flange, the base flange of one of said sections beingadapted to exten'dacross and bear 'up n the base 'flange of the othcr,--the innermfsaid base flanges having a. pluralityofbayonet.

combination of arts as are. hereinafter set forth and descri edand more particularly Referring to the drawingsF- I Figure 1 is a vertical section of aportion; of a vehicle wheel having my improved demountable rim 1 thereon v Fig. 21st bottomxview of. sector bf saidnm .1 I v V 3- is a cross section, of the rim and felly upon an enlargedseale, showing the V preferred'form of the int ention; v

Like letters refer to lik'e parts throughout the several views.

Int'he embodiment of m y invention shown '-inthe accompanying"- drawin the felly of the wheel is indicated at b. I long the inner edge of the'; f cl ly b, I provide a retaining flange a extending substantially radially of the wheel from a seat'd carried. by a sheathing stripe permanently secured to the fell The seaticl projects laterally beyond thesi e. of the felly and is sup orted at different points about the folly y a plurality of clamp brackets cl, one of which is shown in Figs. 3 and 4 respectively. The said brackets are held in position upon the felly by means of a bolt (Z passing transversely through the felly.

The demountable rim is mounted upon the sheathing strip, or metal felly 'bande, with the inner edge thereof bearing. upon'the seat 11 and the outeredge thereof supported by removable clamp brackets f detachablymounted upon the telly in the proper re1ation to the demountable rim by means of'the bolts d? and nuts d carried thereby. Said rim comprises two separable, circular sections 9 and h adapted to be so connected as to be capable'of being mounted upon, and removed from, the wheel simultaneously.

Thesection 9 consists of a base flange z of a width suflicientlygreat to span thegap between the beads of the ordinary tire shoe, 21c upper face of this flange being cont1nuus and smooth to" avoid'all' possibility of ob; cutting of an inner tube by reason of omjections extending outwardly therefrom. Projecting from the base flange i and subas a support for outer base flange, and operative connections between s tantiallyra-dially thereof is a side flan e whichimay be of' the no rim cut,

--clen cher or any other desired type.

The demountable rim section ghasalong the under. face thereof, and inwardly pro- 'Jecting, a plurality of studs 7c by meansof which the inner section it of said rim maybe connected'with said section 9 int-a manner to permit the quick and convenient connection or separation of these'sections' Prefer-1' ably these studs 7:; ,are provided'mwith en-' :larged semispherical heads 70 'adapted'fltd bear upon the sheathing e to aflordfa; support for the demountable rim having a contact area sufficiently restricted "to avoid excessive binding of the demountable. rim .upon

the said sheathing. strip e or the freezing of the demountable' rim and said strip.-

The studs also serve to properly position thede'mountable. rim so as to facilitate the I EOSltlOIllIlg and withdrawal of the clamp rackets f.

The base flange i has therethrough' an openin z". through which the valve stem of the in atabletire is adapted tobe-insrted.

and with; a side flange m similar .to the side flange j ofithe section 9. {The flange? is provided with a plurality of bayonet, slots; n

adapted respectively to coiiperat e with the studs 70, theseslots opening outwardlyof said flan e so as to permit the complete "sedpaa ration o the two sections g'h. In a tion to the bayonet slots n the flange l-is vided with a bayonet slot n adap ito the valve stem when afl'ord clearance for. se arating sai d sections.

heba-se flange l of the'section. h is preferably stepped; adjacent the flange in as at 0 to form a shoulder against which the base flange ii is adapted to abut.
